Cloudflared - one domain, two HA with separatate IP-providers

Possible a stupid question, but can I use the the Cloudflare/cloudflared solution with two different HA installations using one domain?
I have set up a working solution for my home, based on local tunnel, but might need/want to set up an additional HA installation at my parents house. There is no need to integrate the two installations, I just want to be able to monitor/support theirs.

Both IP-providers only supply CGNAT networks.

I am doing it with no problems. You need to use subdomains of course and set separate CNAME record in CloudFlare’s DNS for each installation.

Subdomains are no problem, I already have that for my main installation.

I’ll have to read up on CNAME @ CloudFlare.
